Abstract
The utility model discloses a novel anti-corrosion foundation bolt, which comprises a bolt, a gasket, a nut and a protective cap, wherein the surfaces of the bolt, the gasket and the nut are sequentially provided with a zinc-impregnated layer and anti-rust oil from inside to outside, the outer end part of the bolt is provided with the protective cap, and the protective cap completely covers the nut, the bolt and the gasket.
Description
Technical Field
The utility model relates to the field of land construction of offshore oil jackets, in particular to a novel anti-corrosion foundation bolt.
Background
The prior anticorrosive forms of the foundation bolts mainly comprise electrogalvanizing, hot galvanizing, teflon and the like. Wherein, the electrogalvanized coating has lower adhesive force, general corrosion resistance and serious pollution in the process of production. The hot dip galvanizing process has low cost, high efficiency and large treatment capacity, however, due to high treatment temperature, the hot dip galvanizing can affect the welding performance and the processing performance of materials, the thickness of a coating is uneven, the controllability of the thickness of the coating is poor, the adhesive force is poor, the coating is easy to fall off in construction, and the pollution in the production process is serious. The Teflon coating has poor adhesive force and poor temperature difference resistance, and the coating is extremely easy to break in construction, so that the anticorrosive effect is lost, and the cost is high. In addition, the bolt only adopts an anti-corrosion mode, the anti-corrosion effect is not durable, and the guarantee is not strong.
Disclosure of Invention
The utility model provides a novel anti-corrosion foundation bolt, and provides multiple guarantees for bolt corrosion prevention.
In order to solve the technical problems, the utility model provides a novel anti-corrosion foundation bolt which comprises a bolt, a gasket, a nut and a protective cap, wherein a zinc-impregnated layer and anti-rust oil are sequentially arranged on the surfaces of the bolt, the gasket and the nut from inside to outside, the protective cap is arranged at the outer end part of the bolt, and the protective cap completely covers the nut, the bolt and the gasket.
Further, the surfaces of the bolt, the gasket and the nut form a zinc-impregnated layer in a hot zinc-impregnation mode.
Further, the protective cap is sealed with the base surface of the bolt installation position.
The utility model has the technical effects that:
the utility model comprises a bolt, a gasket, a nut and a protective cap, wherein the surfaces of the bolt, the gasket and the nut are sequentially provided with a zinc-impregnated layer and rust-proof oil from inside to outside, the outer end part of the bolt is provided with the protective cap, and the protective cap completely covers the nut, the bolt and the gasket.

Detailed Description
The present utility model will be further described with reference to the accompanying drawings and specific examples, which are not intended to limit the utility model, so that those skilled in the art may better understand the utility model and practice it.
The embodiment of the utility model discloses a novel anti-corrosion foundation bolt, as shown in fig. 1, which comprises a bolt 1, a gasket 2, a nut 3 and a protective cap 6, wherein the surfaces of the bolt 1, the gasket 2 and the nut 3 are sequentially provided with a zinc-impregnated layer 4 and anti-rust oil 5 from inside to outside, the outer end part of the bolt 1 is provided with the protective cap 6, and the protective cap 6 completely covers the nut 3, the bolt 1 and the gasket 2.
The surfaces of the bolt 1, the gasket 2 and the nut 3 are formed into a zincification layer 4 by a zincification method.
The protective cap 6 seals against the base surface of the mounting location of the bolt 1.
The bolt 1 and the nut 3 washer 2 are first subjected to a zincification treatment. The hot zinc infiltration technology utilizes the infiltration diffusion effect of metal atoms in a heating state to infiltrate zinc element into the surface of the steel member to form alloy protection layers with different Zn-Fe ratios, and the corrosion resistance is good. The thickness uniformity of the plating layer is good, the plating layer can be accurately controlled, the corrosion resistance is strong, the corrosion resistance advantage of the zinc-plated product is obvious, the zinc-plated product is 5 to 10 times of that of the electro-galvanized product, and the specific heat zinc plating is improved by 30 percent. High binding strength with the matrix metal and good wear resistance and scratch resistance.
After the zinc impregnation is finished, the surface of the base material is coated with the rust-proof oil 5 to form a layer of compact protective film, so that the rust-proof capability and the salt spray resistance of the fastener are greatly enhanced. The rust preventive oil 5 has the advantages of good use effect, convenient use, low cost, easy construction, simple operation and the like.
The bolt 1 is coated with the rust-proof oil 5 and then the protective cap 6 is installed, the protective cap 6 can isolate the bolt 1 from air and moisture, the corrosion resistance of the bolt 1 is improved, and meanwhile, the protective cap 6 can resist ultraviolet irradiation, so that the service life of the bolt 1 is prolonged.
Compared with the prior single anti-corrosion form, the composite anti-corrosion form has stronger anti-corrosion capability, and can greatly improve the anti-corrosion service life of the bolt 1.
The above-described embodiments are merely preferred embodiments for fully explaining the present utility model, and the scope of the present utility model is not limited thereto. Equivalent substitutions and modifications will occur to those skilled in the art based on the present utility model, and are intended to be within the scope of the present utility model. The protection scope of the utility model is subject to the claims.
